Eric Vicenti a3085464f6 NavigationExperimental
Summary:
A new API to unify internal navigation. Also addresses a highly-rated community 'pain': https://productpains.com/post/react-native/better-navigator-api-and-docs/

Offers the following improvements:

- Redux-style navigation logic is easy to reason about
- Navigation state can be easily saved and restored through refreshes
- Declarative navigation views can be implemented in native or JS
- Animations and gestures are isolated and now use the Animated library
